I'm asking for help on WinAPI. Need to be able to do these two actions in MT5.

Call the menu shown and select to save the report.


Call the menu shown and select to load a set file.


In MT4 this kind of thing is very easy. In MT5 it is not.

I.e. you just need to open menu and select an appropriate option. But it cannot do that.


Sounds like it should be.

 

If you record a Message log to call the context menu for task 2, you can get the following result:


Try to call this menu programmatically viaSendMessage WinApi.

Not successful.

  static const int ControlID[] = {}; // Пробовал углубляться по дереву окон - не помогает.

  user32::SendMessageW(Handle, 0x10C1, 0, 0);
}

It didn't work out

You're probably using the wrong handle.
The charts are implemented within the MDIClient object, you need to go up to the root terminal.exe window and then go down through the windows to the highlighted "SysListView32" and use its handle.
There may be an easier way, try it out...

Got to the Handle, didn't help.

void OnStart()
{
  static const int ControlID[] = {0xE81E, 0x804E, 0x28EF, 0x28FE};
  GET_HANDLE
  
  Print(Handle); // Распечатал хендл.
  
  user32::SendMessageW(Handle, 0x10C1, 0, 0);
}


Probably a different Message.

 

A question that has long plagued me is how to motivate the thought process correctly

if (value[0] > value[1]

or vice versa

first zero and then the next?

 

Hi, Can you tell me why my terminal behaves like this onVMware x64?

It feels like it happens more often when the terminal is loaded with chart objects.

e.g.: trades, calendar events

Indicator after a malfunction

After some time the indicator stops working properly:

- M1 chart;

- any indicator (in the figure standard Moving Average);

- tested on three machines.

If you change the schedule period, everything falls into place.

For me this is critical as I use signals from chart indicators in my EA.

Specify the data:

copy three lines from "Log" tab (select three lines -> right mouse click -> Copy)


and paste it into your message. It should look like this:

It seems to happen more often when the terminal is loaded with graphical objects.

for example: trades, calendar events and small timeframes

Got it with WM_CONTEXTMENU.
Slightly tweaked the code, it's easier to debug and can be reused:

#include <WinAPI\winuser.mqh>

#define  GA_ROOT            0x00000002
#define  WM_CONTEXTMENU     0x007B


#define  PRINT(x) ; Print(#x, ":", string(x))
#define  PRINT64(x) ; printf("%s%s%#.08x", #x, ":", x)


long GetHandle(long handle, int &controls[]){
   long next_handle = handle;                                                                        
   for (int i = 0; i < ArraySize(controls); i++){
      next_handle = user32::GetDlgItem(next_handle, controls[i]);
      PRINT64(next_handle);
   }           
   return next_handle;                
}
  

void OnStart(){
  long RootHandle = user32::GetAncestor(::ChartGetInteger(0, CHART_WINDOW_HANDLE), GA_ROOT);
  PRINT64(RootHandle);  
  
  int controls[] = {0xE81E, 0x804E, 0x28EF, 0x28FE}; 
  long handle = GetHandle(RootHandle, controls);
  PRINT64(handle);
  
  
  //PRINT(user32::SendMessageW(handle, WM_CONTEXTMENU, 0, -1));
  PRINT(user32::PostMessageW(handle, WM_CONTEXTMENU, 0, -1));
  PRINT("Sleep");

  Sleep(10 * 1000);
}
